When the 4-way beeper switch is moved to the left, the power of engine #1 is what, engine #2 is what, and the rotor RPM remains what?

When the 4-way beeper switch is moved to the left, the power of engine #1 is what, engine #2 is what, and the rotor RPM remains what?

• A. increased, decreased, rotor
• B. decreased, increased, rotor
• C. increased, increased, rotor
• D. decreased, decreased, rotor

Answer: (A)

Moving the four-way beeper switch to the left reallocates load between the two engines. It increases power to engine with the left position and decreases power to the other engine. The rotor is driven by both engines, and the system’s speed governor keeps the rotor RPM steady despite the change in how the load is shared. So you end up with engine #1 delivering more power, engine #2 delivering less, and the rotor RPM staying unchanged.
